We present tables for self-diffusion coefficients of the Lennard-Jones liquids and gases for various model formulas in the modified free volume theory of diffusion in the case of reduced temperatures $T^{ \ast}=6.0$, 4.0, 1.3, 1.0, 0.8, 0.7 with reduced density ranging from $\rho^{ \ast}=0.025$ to 1. Their accuracies are compared with the molecular dynamic simulation results. In the gas and liquid density regimes, the formula $D_{ CERC}$ for the self-diffusion coefficient is accurate within maximum 4% of the molecular dynamics simulation values reported in the literature. It is the most reliable among the formulas presented
